PURPOSE Although the pathogenesis of inflammatory bowel disease (IBD) is unclear, autoimmune processes seem to play roles in IBD because several types of autoantibodies have been found in it. Calreticulin (CRT) is a soluble Ca2+ binding protein which is present in a wide variety of cells. CRT is localized mainly in the endoplasmic reticulum and is often a(More)
BACKGROUND Neutrophil elastase (NE) is a proteinase in granulocytes and plays an important role in the pathogenesis of inflammatory disorders. It has been reported that NE activity is elevated in both colonic mucosa and blood in inflammatory bowel disease (IBD) patients, and that it can act as an aggravating factor in IBD. To develop novel therapies for(More)
We report a case of HLA-B52-positive Behçet disease accompanied by multiarterial lesions. A 24-year-old woman was suffering from sporadic high fever and recurrent oral and genital ulcers, and laboratory data revealed severe inflammation. A diagnosis of Behçet disease was made. Magnetic resonance angiography, ultrasound study, and computed tomographic(More)
We report a case of ulcerative colitis (UC) that occurred during the course of rheumatoid arthritis (RA). A 29-year-old woman with a 25-year history of RA was hospitalized for high fever, abdominal pain and hematochezia. Colonoscopy revealed erosive and reddish mucosa from the distal transverse colon to rectum. Histology revealed cryptitis (mainly caused by(More)
Estrus induction is an important step in embryo production. It has been difficult to induce estrus in miniature pigs by intramascular (i.m.) injection of prostaglandin F2alpha (PGF2(2alpha)) in the early luteal stage of the estrous cycle. In the present study, we injected two different doses of PGF2(2alpha) i.m. and into the submucosa of the vaginal(More)
A 52-year-old man noticed physical weariness and anorexia in November 2008. Severe anemia was found. Pneumomediastinum was detected using x-ray and CT scanning. Esophagogastroduodenoscopy revealed a submucosal tumor with a deep ulcer in the anterior wall of the upper stomach, causing anemia. Partial gastrectomy was performed because microperforation was(More)
